1) Hogerheijde's counter-rotating disks:
" I might have a neat picture for the CARMA booth, with
recent results on
HCO+ 1-0 and 3-2 emission from a contracting, rotating disk around
a young
star. It contains data from BIMA (HCO+ 1-0 and 3-2) and OVRO (1-0);
the
HCO 1-0 image contains data from both arrays ("virtual" CARMA)."

b) Planned move of the BIMA antennas (joke!)
3) Fabian Walter's contribution:
"dwarfs are a good example why we need more powerful radio interferometers
such as carma. the reasoning would be that dwarf galaxies
are important
targets to study since they are believed
to be the nearby counterparts of the young galaxy population at
large
redshift (metal poor, small, blue, actively forming stars). the
fact that
they are small and metal poor makes it so far very difficult to
study
their molecular gas phase which is vital to understand star formation
in
these systems. only the next generation of mm interferometers such
as
carma will allow us to study the properties of the interstellar
medium in
these objects in much greater detail."

5) My contributions: - BIMA SONG Gallery:
" CARMA will allow us to get an instant photograph of the molecular
gas in nearby and distant galaxies. Today, with the
existing arrays such studies push the limits of technology - the
44 galaxies BIMA survey took over a year and a half. And the OVRo
survey which imaged a smaller region in 20 galaxies also took a significant
amount of time. CARMA will not only
do this faster, with higher sensitivity but it will also allow for
imaging of larger areas of the galaxies. We will be able
to study the morphology and kinematics of the molecular gas, the
fundamental fuel for star formation and galaxy evolution."

9) Micol Christopher's Galactic Center Data
The center of our Milky Way Galaxy contains a black hole with a mass
of
several million suns. This massive black hole, which lies
only 20,000
light years from earth, provides astronomers with a unique opportunity
to
study the environements around massive black holes, which is made
particularly interesting because many galaxies are thought to contain
such
black holes in their centers. Using OVRO, we mapped molecular
gas (HCN)
and ionized gas (appearing as continuum emission) within the inner
10
light years of our galaxy. The HCN distribution is shown by
the color
image and the continuum emission by contours. HCN particularly
emphasizes
regions of high density. From the image one can see clearly a ring-like
structure of molecular gas surrounding the galactic center; this
has
become known as the Circumnuclear Disk. Also interesting is
the interplay
between the ionized and molecular gas - along the western part of
the
ring, the ionized gas appears to mark the inner boundary to the
ring,
while to the north the ionized gas seems to be "escaping" through
an area
of lower molecular gas concentration in the ring. With OVRO,
we are also
able to measure the radial velocities of the HCN, and with this
information we hope to model the action of the molecular gas, both
in its
likely orbit around the galactic center but also in its possible
infall
onto the black hole.
10) Shardha's NGC 2782 contribution
"Theory and simulations suggest that a nuclear stellar bar provides
an
efficient way of fueling gas into a central starburst or AGN.
OVRO CO (1-0) observations of NGC 2782 reveal one of
the first cases
where a nuclear stellar bar is caught feeding molecular
gas into a
central starburst. The CO map (contours) at 1.5''
resolution overlaid
on the 5 GHz radio continuum (greyscale), shows a clumpy bar-like
molecular
feature of mass $2.5 \times 10^9$ $\msun$ with weak bar-like streaming
motions.
The gas lies on the leading side of a nuclear stellar
bar where gravitational
torques will cause it to lose angular momentum and fuel the
central starburst
which is driving a dynamically young outflow."
To elucidate the origins of high nuclear star formation rates, a
comparative
study of the molecular gas in the brightest nearby starbursts comparable
to M82,
and control non-starbursts has been conducted. The figure
shows the CO
intensity (contours) of typical resolution 2'' (100--200
pc) on the star formation
(greyscale). In the starbursts which have a high SFR
per unit mass of
molecular gas, the peak gas density is high (1000 to
3500 $\msun$ pc$^{-2}$), and the
local gas density is close to the Toomre critical density
for the onset of
gravitational instabilities. Conversely, in the non-starbursts,
sub-critical densities
and large local velocity gradients or shear appear to inhibit
star formation
in several gas-rich regions.

13) Hot cores from Friedrich Wyrowski
"Hot Core figure: Subarcsecond resolution BIMA observations of the
1.3mm dust continuum toward hot core/ultracompact
HII regions
resolve sites of massive (proto) stars
before (G9/G29) or
shortly after (G10) the formation of ultracompact
HII regions
as seen by the 1.3cm free-free emission
(Cesaroni et al. 1994/1998).
Close to the dust cores detected with BIMA,
other more evolved
UCHIIs have already dispersed their parential
gas and dust
reservoir. The spectrum in the lower left
panel shows many lines
of highly excited complex molecules as
typical characteristics
of the hot molecular gas surrounding massive
(proto) stars."
